"When I learned about Elco Jacobs’ amazing ShiftPWM Arduino Library, I knew all I needed was a little general purpose driver board to light all that LEDs up. the library basically uses shift registers and a high frequency serial signal in order to PWM control a lot of LEDs on just three Arduino pins. handy enough, I was introduced into etching PCBs at the same time, so there it was, my first etching project."

"In this tutorial, I’m going to harness the awesomeness of Raspberry Pi to build a moisture sensor for a plant pot. You will be able to monitor the sensor locally on the LCD or remotely, via ControlMyPi.com, and receive daily emails if the moisture drops below a specified level."

"This project demonstrates the ability to navigate a user based on synthesized directional audio which allows the user to move to a known location without the use of a visual aid. The module uses a GPS, a digital compass, and an ATmega32 to generate sound based on the direction that the user must turn in order to face the correct direction."

"This is a circuit to automatically blink the turn signal lights of a car a number of times after a short tap of the turn signal handle. This feature is often found in newer cars these days, but not in my 2000 Volkswagen Passat. Instead of buying a new car, I decided to upgraded it with an Atmel ATtiny12."

"Bluetooth has become Ubiquitous these days Bluetooth Wireless technology is present is Most mobile phones today as well as in laptops and in desktop PCs. And If your PC or laptop doesn’t have it then you can get a Bluetooth USB dongle for cheap! Wouldn’t it be interesting if your mobile phones /PCs could talk to your Microcontroller Projects?"

"Behold: a complete Nintendo Entertainment System cloned in an FPGA! Originally written in VHDL by Brent Allen and myself while at Washington State University, I’ve recently revisited this project and begun both: rewriting it in Verilog, and adding many new features."

"This is a simple JTAG interface, which can be connected to computer’s parallel port. It is originally designed by Xilinx to program FPGAs and CPLDs… It is a one-sided PCB, the bottom side is made from wires."

"The mood that the ‘Magic Crystal Mood Ball’ gives to the user is based on measuring his temperature and changing the color of the RGB LED to the its respective color. As in a mood ring, I set different colors for different temperatures. The temperatures coincides with mood state that the person is in."

"Last time I went through junk in the basement I found old ZX spectrum.This was the time I got the great idea. Have the ZX spectrum implemented in FPGA…..As for the hardware part I had this SparkFun’s Spartan 3 breakout board. 500k gate FPGA that should be big enough most home made projects."

"Inspired by Andre’ Michelle’s Tone Matrix flash applet I decided to make a physical version – i.e. a box with buttons, flashing lights and knobs to turn. I wanted 16×16 – the Bliptronic 5000 just doesn’t have enough lights."
